HDD spins down even if disabled

[dezo]

Hi,
I'm running LMDE UP6 with MATE and set the HDD to never spin down, both on battery and on AC. On AC it works fine, but when I'm on battery, the hdd spins down anyway no matter what is set in power management. It was in UP5, broken on UP6. Two laptops, the same behaviour.
Any idea how to fix this?

Even
hdparm -S 0 /dev/sda
does not help...

Btw,

Code: Select all

hdparm -B 254 /dev/sda

works though. But still looks like a bug in UP6/Mate 1.4.

there's a tool called laptop-mode-tools which overwrite the hdparm when the power changed to battery. you need to change the value on laptop-mode-tools.

There's a checkbox for that in mate-power-preferences so I assume it should work without any other tools.

what I mean in my previous post is that laptop-mode-tools is installed by default. even if you didn't see this tool listed on your package list, some part of this tool already installed on your system. this tools overwrite any setting you've made with other app/tools/command. if you want to permanently disable hdd spin you might need to edit that file.

you can go into /etc/pm/power.d/ and see whether if laptop-mode file exist.

Nope, that dir is empty...
